CYCLE-LAMP.

Specification of Letters Patent.

Patented Apr. il, 191W.

Application led January 24, 1916. Serial No. 74,014.

To aZZ whom t may concern:

Be it known that I, FRIEDERIGK lVIND- I-rAUsnN, engineer, a subject of the King of Prussia, and a resident of Dusseldorf, Germany, have invented certain new and useful Improvements in Cycle-Lamps, of which the following is a speciication.

The present invention relates to an improved acetylene-lamp, especially destined for cycles, and has for its purpose to provide a lamp of simple, compendious and durable construction.

The hitherto known lamps for cycles have lmany disadvantages, mainly because they are composed of a. great number of separate parts soldered or riveted together, which due to the repeated shocks to which the lamps are subjected in driving, commonly after some time loosen and then are lost or have need of great repairing work for being again fastened. Further the lamps on sale are quickly going to ruin on account oi' their light, thin and feeble structure, and therefore become useless in a short time. The reason for this is that the single parts of the lamps are made of thin brass or ironsheet which is naturally not able to resist great forces and wearing, thereby causing an untightness of the water-tank and many other defects of the lamps.

All these disadvantages are avoided by the present invention, the lamp forming in its main parts a single solid body of castmetal. The lamp, therefore, consists in a single piece; carbid-box, water-tank, reflector, chimney and the gas-supply to the burner. Furthermore the new lamp, by suitably choosing the metal for yits construction-mainly aluminium and copper-is so stable, that it will Vwithstand the greatest shocks.

The invention is illustrated by the accompanying drawing in a form of construction given as example and showing a cycle lamp in longitudinal section.

The cast body a comprises mainly three chambers or hollow parts, viz.: a chamber al below serving as carbid-receptacle, an upper chamber a? serving as water tank, and a lateral chamber a3 forming the reflector. At said body a the parts and means for working of the lamp are arranged partly detachable at the interior, partly on the outside easily accessible.

The carbid-chamber a1 is closed at its base the main parts, namely the.

by a bottom-plate Z9 screwed on and thus detachable. In the interior, a receptacle c is supported, and in the said receptacle a hollow body Z having several holes e in its wall, is also supported. The upper part of the bodycZ above the carbid is surrounded b y a flat ring or plate f upon which is mounted a spring g which presses upon the plate and thereby holds down the carbid and prevents it from being weakened while in use. Above the body (Z is a screw ZL which will be described more clearly hereinafter. On said screw is arranged a wing-nut rl which holds a disk i and a felt plate j against the cross-wall Zr which divides the chamber c1 from the chamber a2. In the disk t' and the plate j*I are small openings for the passage of the acetylene-gases, which are puried by the felt.

The water which drops through a groove Z along the lower part of the closing pin m down into the hollow body CZ and penetrates through its openings e into the carbid receptacle c. The pin m is at its top end provided with a handle a and passes through a central opening ina nut o which is screwed into the cover and is of such a diameter, that when it is unscrewed, the bottom screw t will move through the corresponding opening in the cover-wall of the water-chamber a2. A stopper p screwed in said wall serves for filling purposes.

The screw 7L is provided with a cone shaped head which serves as a valve for tightening the screw at its passage through the wall 7e. Furthermore said screw holds and supports the pin m which is screwed therein with its lower end in such a position that the groove Z extends upwardly and into the water chamber and ends below in the central perforation of the screw ZL where a small tube g is inserted, projecting below and leading the water in the hollow body CZ. If the pin m should break by too quickly turning it, the screw Zzy may be removed by means of a screw-driver or the like, from above through the central opening in the cover-wall of the chamber a2 and then pin m may be replaced by another.

For suitably supplying gas to the burner r the channels s and t which cross each other are formed in the body a. The channelsextends from the channel t to the burner r wall of the water-chamber a2 the channel7 and is closed by a screw o.

which is screwed into the larger top-end of The channel t extends from the interior oi' the carbid chamber' al in the plane oi' the felt plate to the outside and is here closed by a screw fw. After unscrewing the screws v and fw the channels s and t can be quickly and easily cleaned.

l claim as new:

A casted acetylene lamp comprising a body portion including an upper water Copies of this patent may be obtained for chamber, a reiector integral therewith, a lower carbid chamber integral with the Water chamber and in communication theren With, the lower end of said carbid chamber having a threaded periphery, and a threaded closure adapted to cooperate with the threaded periphery of the carbid chamber for securing the same thereto.

Signed at Cologne, Germany, this 15 day of October, 1915.
